Hyperconjugation is defined as No bond resonance. The concept of hyperconjugation arose from the discovery of electron releasing pattern for alkyl groups. It involves sigma electrons of C-H bond. Greater the number of C-H bond ( alpha -hydrogen atom w.r.t. double bond) more will be hyperconjugative structures, more will be stability Heat of hydrogenation of alkene are affected by hyperconjugative effects. Which of the following is incorrect hyperconjugative structure?

Hyperconjugation describes the orbital interactions between the pi -system and the adjacent sigma -bond of the substituent group(s) in organic compounds. Hyperconjugation is called as Baker and Nathan effect. The necessary and sufficient conditions for the hyperconjugation are: (i) Compound should have at least one sp^(2) -hybrid carbon of either alkene, carbocation or alkyl free radical. (ii) alpha -carbon with respect to sp^(2) -hybrid carbon should have at least one hydrogen. Hyperconjugation are of three types: (i) sigma(C-H),pi -conjugation, (ii) sigma(C-H), positive charge conjugation, (iii) sigma(C-H) , odd electron conjugation. The hyperconjugation may be represented as, Number of resonating structures due to hyperconjugation =(n+1) , where n is the numebr of alpha -hydrogen. Greater is the number of such forms, more is the stability of the species under consideration. Stability of alkyl carbocations can be explained by
